Roberto, a worker from Guadalajara, bought a motorhome at an auction in San Leandro for more than $5,000. Minutes after paying, he says he drove to Oakland and noticed smoke coming from the rear. The company that sold the vehicle refuses to honor the warranty, for which he paid $200. According to the owner, after firefighters arrived, valuables were stolen from the motorhome and the vehicle was vandalized. A lawyer notes that in an auction purchase, the risk falls on the buyer.
